Note: I am not always sure about the english names.
The abdomen goes from the arches of the ribs to the iliac crest and the front of the pelvic ring. The abdomen muscles are the external oblique, the internal oblique, the transversus abdominis and the rectus abdominis. Rectus abdominis goes from the chestbone and the lower ribs cartilage, in a straight line to the upper ridge och the pubic bone. It contracts as we do sit-ups. The other three muscles forms the abdomen wall. They make the abdomen wall strong because of their different directions of their fibres and that also stops the organ from falling out through the wall. When the muscles contracts they become a strong defence if you’re hit in the abdomen. Contraction of the abdomen muscles helps with breathing and defecation. There’s also the inigual band that goes from the upper comb of the hipbone to a knuckle on the pelvic bone.
There’s also the abdominopelvic cavity, which is a cavity between the diaphragm and the pelvis. In the cavity lies the liver, stomach, spleen, gallbladder, pancrea, småll intestine and most of the large intestine. Both the abdomens organs and the abdomen wall is surrounded by a membrane that contains of two layers. Between these layers lies the pelvic cavity, that is a liquidfilled part. Because the membrane secretes liquid, the organs can move without any mentionable friction. There’s also something called the mesentry. It is a continuous set of tissues which is formed by the double fold of peritoneum that attaches the intestines to the wall of the abdomen and between the layers lymph, nerves and blood vessels runs.
Looking at it from cranio sacral therapy I can for example see if the inigual band is tight and pulls on the pelvis. By relaxing the inigual band I help the pelvis to move. I know this can sound strange for some, but the techniques I have learned is largely about making the body relax, so that it can move in the way it is created for. Unfortunately, we don’t learn to listen to our body and to understand it, so that we can do things to avoid our body to get stuck. And after all the positive reactions I have seen treating both my own and others bodies, I only get more and more fascinated by how wise our body is and how it adjust itself, if it is given the right settings.
